Directorate General of Meteorology provides a lot of climate data to the public. The website has a section for providing simple weather details for specific cities in Oman and shows the temperature changes for the next three (not five) days for each city. ( http://www.met.gov.om/opencms/export/sites/default/dgman/en/weather-chart/oman-cities/index.html ) There is a section for historic data for the past 12 months. The website also has a more elaborate interactive map that allows the user to overlay different weather layers and playback the predicted changes for several future days. ( http://www.met.gov.om/opencms/export/sites/default/dgman/en/weather-chart/map-data/ ) The website is difficult to navigate and browsing by map is not intuitive and very slow. Also, the raw data does not appear to be available for download directly.

Not all required data is considered to be uploaded online, because wind strength and direction are not included in the forecasts for the following two days.
The website contains verbal and iconic forecasts. The forecasts for "Oman Cities" are in HTML, well-structured and the icons embedded in HTML are named in a way that makes them easily understandable if automatically retrieved.
There is no download function. Some of the forecast icons (precipitation) make it hard to assess how much rain is going to fall (they are generic statements that rain is gonna fall).
There is only a copyright notification, but no open license. The terms of use are unclear. The data does not qualify as openly licensed.
